As previously stated, this invention relates to improvements in theribbon spool tensioning and locking means shown in our application filedJune 25, 1931, and therefore only that much of the typewriting machineis illustrated in the drawings as will be. necessary to an understandingof the present invention. The typewriting machine includes a main frameA on which a carriage B is supported for letterspace movements. A.platen C is fixed to the lower end of a collatin frame D pivoted on thecarriage to swing orwardly and rearwardly to effect a rearward and foronthe carriage below the platen, and thence upwardly past the platen andhave their upper edge portions clamped to a. truck J which 18 mounted onthe collating frame D for line space movements, the truck bein linespaced by the lever E by a mechanism s own in our copending application.A spool supporting frame K is disposed in rear of the main frame A andis attached to the carriage to move therewith, the frame K carryingrollers 7, 7 which ride along a rail 8 attached to the main frame A. Aplurality of ribbon spools L are rotatably supported on a shaft 9 fixedto the frame K, and the carbon strips or ribbons M are led from thespools forwardly along the left side of the carriage, thence along andin front of the platen and in rear of the main ribbon G and ininterleaved relation with the work sheets, and thence rearwardly alongthe right hand side of the carriage to a ribbon feeding means N whichincludes cooperating feed rolls 10, 10. The ribbon feeding means N isactuated from the collating frame D by connections shown in ourcopending application. Means are provided for individually and normallytensioning the spools against feedin rotation and other means which arenorma y ineffective, are provided for individually and simultaneouslylocking the spools against feedin rotation at a period of timeimmediatel be ore the ribbon feeding means has complbted its movementwhereb the ribbons will be rendered taut before the work sheets are linespaced thereby preventing the carbon strips from being dragged upwardlytherewith. Means are also provid ed for simultaneously releasing thetensions and the clutch pawls whereby the spools may be readily removedfrom or applied to the .spool supporting shaft without any interference.

The above construction is shown and claimed in ourco-pendingapplication, and the present invention relates to a differenttensioning and locking means for the spools and to means for releasingthe same from the spools.

The spool supporting frame K includes front and rear walls or plates 11and 12 respectively, which are rigidly connected by spaced upper sidebraces 13, 13 and spaced lower side braces 14, 14, the latter beingprovided with upstanding flanges 14*, 14* along their outer side edgesthereof. The spool supporting shaft 9 is fixedly secured at its frontend to the front plate 11 and the rear free end of the shaft is locatedcentrally with respect to an opening 15 formed in the rear plate 12,

the opening being of a size sufficient to permit a ribbon spool -L to befreely passed therethrough.

Each s ool L comprises a hub 16 having a disc mem er 17 fixed theretoand provided with a serrated clutch periphery 18. Mounted on the hub 16is a core 19 having a transverse opening or seat 20 which receives a pin21 fixed to the disc member 17,to maintain the core and disc againstrelative rotation yet permitting of the core being removed from the hubor positioned thereon.

Disposed directly below the horizontal spool shaft 9 is ahorizontalbearing rod 22 having its ends secured to the front and rear plates 11and 12, the rod being disposed in a horizontal plane below the opening15 of the rear plate. Disposed above the rod 22 and below the spools Lis an arcuate plate 23 which is sprung into place against the lower sidebraces 14, 14, and is concentric with the axis of the spool supportingshaft 9. The plate 23, as viewed in Figure 7, is provided along its sideedges with depending flan es 23 and 23 respectively, the former being atthroughout its height, and the latter being formed with an inwardlycurved lower end portion 23. When positioning the plate 23 on the braces14, 14, the flange 23 of the plate is first positioned against the innerface of the flange 14 of the associated brace 14, and then the otherflange 23 is pushed downwardly and sprung into place against the flange14 of the other brace 14, the lower curved portion 23 facilitating the oeration. Thus the plate 23 is yieldably but rmly retained in position onthe braces 14, 14. A series of openings 24 and a series of openings y 25are respectively formed in the arcuate plate 23 on opposite sides of therod 22, and are disposed in parallelism therewith. These openings arearranged in pairs, one opening 24 and one opening 25 being in registerwith the disc member 17 of each spool L. Associated with each opening 24is a tension lever O which is in the nature of a bell crank lever andincludes spaced parallel members of identical construction, each membercomprising a depending cam arm 26 and a horizontal arm 27, the latterterminating in an upstanding arm 28, and both arms28 being connected bya web 29. The lever O is journaled on the bearing rod 22, there beingalined bearing openings 30, 30 formed in the horizontal arms 27, 27adjacent the depending cam arms 26, 26 for receiving the bearing rod.The upstanding arms 28,28 are provided adjacent their upper ends, withalined bearing openings 31, 31 to receive the hub 32 of a frictionroller 33 having a serrated periphery 34, the hub and roller being intight contact to rotate in unison. The hub is also slidable in the bearing openings 31, 31, and one end of the hub rotation of the roller 33 isresisted by two frictional brakes, the first being located between thecircular surface 36 of the hub and the upper end of the spring, and thesecond being located between the roller 33 and the arm 28 opposite thespring. These serrated rollers 33 are yieldably retained in engagementswith the serrated peripheries 18 of the disc members 17 by coil springs38, and the feeding rotations of the spools are individually resisted bythe two frictional brakes above noted.

A plurality of lock levers P are also fulcrumed on the bearing rod 22,there being one lever for each spool. Each locking lever P is in thenature of a-bell crank lever consisting of a de nding cam arm 39, ahorizontal arm 40, and locking pawl 41 which is integral with thehorizontal arm and extends upwardly therefrom and between the endsthereof. The serrations 34 of the friction rollers 33, the serrations 41of the pawls 41, and the serrations 18 of the discs 17 are consistentwith one another, and consequently the pawlswill fit the discs forpositive locking contact therewith, and the rollers will have positiveintermeshing engagements with the' discs and therefore there will be noslippage between them. The horizontal arm 40 is formed adjacent thedepending arm with a' ,bearin opening 42 for receiving the hearing r 22.Each lock lever P is located between the spaced bell crank members ofthe associated tension lever O with the pawl 41 disposed on the side ofthe bearing rod. 22 opposite the tension roller 33, and with thedepending cam arm 39 on the side of the bearing rod opposite thedepending cam arm 26 of the tension lever. A plurality of spacingsleeves 43 are journaled on the bearing shaft intermediate the locklevers P and function to maintain the same in register with therespective disc members 17.

Disposed directly below and in parallelism with the bearing rod 22 is acam shaft 44 which is journaled at its ends on the front and rear wallsor plates 11 and 12 of the spool frame K. This shaft is provided withopposite and parallel cam faces 45, 45, and the shaft extends betweendepending cam arms 26 of the tension levers O and the depending cam arms39 of the lock lever P.

Each spring 38 which is connected at one end to one of the upstandingarms 28 of thetension lever O, has its other end connected to theassociated pawl 41 and functions not only to yieldably retain thetension roller 33 in contact with the periphery 18 of the disc 17 butalso to urge the pawl 41 into contact with said periphery 18.

However, the pawls 41 are'normally ineffective and are held againstnormally engaging the peripheries 18 of the .discs 17, by a bail whichincludes a universal bar 46 common to all of the lock levers P. Thisuniversal bar 46 is disposed directly above theonter ends of thehorizontal arms 40 of the lock levers and is pivotally supported on theends of the bearing rod 22 through the medium of a rock arm 47 and alever 48. the lever 48 opposite the universal bar is connected to oneend of a coil spring 49, the other end of the spring being anchored tothe adjacent lower side brace 14 of the spool frame. The tensilestrength of this spring 49 is greater than the combined tensile strengthof all the springs 38, and consequently the universal bar 46 isyieldingly pulled downwardly against the horizontal The end ofarms 40 ofthe lock levers O and the pawls 411 the upper end of the arm 28 of thetensionlever O in order to give maximum tension between the frictionroller 33 and the disc 17,

and the other end of the spring is attached to the lower end of theassociated pawl 41 in order to give a minimum tension to the lock arm Pto permit easy release of said arm from the disc 17 thereby not onlyrendering the spring 49 most effective but also mini- I mizing theefl'ort required to release the pawls from the discs.

In order to lift the universal bar 46 upon swinging of the carriagereturn lever E and thereby permit the springs 38 to effect lockingengagement between all of the pawls 41 and all of the associated discs17, a bell crank lever 50 is fulcrumed on the front wall or plate 11directly above the spool shaft 9. The horizontal arm 51 of the lever isdisposed directly above the lever 48 and is connected thereto by a link52. The upwardly extending arm 53 of the lever is pivotally connected toone end of a link 54, the other end of the link being pivotallyconnected to one arm of 1 carriage return lever, are all fullydescribed;-

in our co-pending application referred to above.

Fixed to the rear end of the cam shaft 44' is an upwardly extendinglever arm 59 which terminates at its upper end in a rearwardlyiextending finger piece 60. Formed in the lever arm 59 below the fingerpiece is an opening or seat 61 for receiving the reduced rear end 62 ofthe spool supporting shaft 9 and thereby provide a support for the rearfreei end of said shaft 9. This lever arm 59 is adapted to be retainedin its normal position against accidental disengagement from the shaft 9by means of a spring plunger 63 mounted-in a barrel 64 which extendsrear wardly from the lever arm 59, the plunger having its front endnormally located in an opening or seat 65 formed in the rear wall 12 ofthe spool supporting frame K. This lever arm 59 has the additionalfunction to rock the cam shaft 44 and thereby simultaneously withdraw orretract all of the tensioning means from their cooperative engagementswith the serrated surfaces 18 of the spool discs 17, and to also furtherretract simultaneously all of the locking pa-wls 41, as shown in Figure7. Thus upon manipulation of the lever 59, the serrated edges of theclutch paWls 41 and the serrated surfaces of the friction rollers 33,are lowered to positions below the arcuate plate 23, thereby ermittingthe spools L to be readily removed rom or applied to the shaft 9 withoutinterference whatsoever.

In the operation of our invention, the work sheetsH are loaded into themachine and the carbonstrips or ribbons M are interleaved therewith infront of the platen C and the free ends of the ribbons are engagedbetween the feed rolls 10, 10 of the feeding means N, after which thelead-in ends of the work sheets are clamped to the truck J. The operatorthen writes a line on the work sheets. The carriage return lever E isthen swung to the right, prior to returning the carriage, and during thefirst part of the swinging movement of the lever, the collating frame Dis swung forwardly and the platen C rearwardly to relieve the normaltight contact relation between the work sheets and the platen. The

ribbon feeding means N is actuated simultaneously with the forwardmovement of the collating frame, and thus the carbon ribbons M are fedagainst the individual tensioning means which are constantly applied tothe ribbon spools. Prior to the completion of the operation ofsaidfeeding means, the locking means for the respective spools isrendered effective, thereby permitting the last partof the movement ofthe feeding means to stretch of the lever the previously moved parts,ex-

cept the truck J, will return to their normal positions.
